stat.tfisher {TFisher}

Construct thresholding Fisher's p-value combination statistic.

Description

Construct thresholding Fisher's p-value combination statistic.

Usage

stat.tfisher(p, tau1, tau2)

Arguments

p

- input p-values.

tau1

- truncation parameter. 0 < tau1 <= 1.

tau2

- normalization parameter. tau2 >= tau1.

Details

Let p_{i}, i = 1,...,n be a sequence of p-values, the thresholding Fisher's p-value combination statistic

TFisher = \sum_{i=1}^n -2\log(p_i/\tau_2)I(p_i\leq\tau_2)

Value

Thresholding Fisher's p-value combination statistic.

Examples

pval <- runif(100)
stat.tfisher(p=pval, tau1=0.05, tau2=0.25)
